Technical Field

[0001] This utility model relates to the field of warning light technology, specifically a warning light with a tension sensor. Background Technology

[0002] Roads and bridges generally consist of several major parts, including roadbed, pavement, bridges, tunnels, and traffic engineering facilities. my country has a vast territory and a large population, and its roads and bridges are extensive. Whether it is the construction or renovation of roads and bridges, especially the planning of subway lines in cities, road and bridge construction is always underway, and warning lights for road and bridge construction are indispensable.

[0003] In response to the potential for roadbed damage and collapse due to water, and the potential for bridge aging and displacement, special warning lights are needed to alert staff. These warning lights are often placed in locations that cannot be captured by surveillance cameras. Traditional warning lights mostly use trigger devices on the side of the roadbed or bridge to activate or deactivate them to alert people. However, this method is only applicable to larger lateral displacements and is difficult to detect for minor displacements. It lacks the ability to perceive potential risks and has significant limitations in its use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a warning light with a tension sensor. This solves the problem that traditional warning lights mostly rely on triggering devices installed on the side of the roadbed or bridge to activate or deactivate them to alert people. However, this method is only applicable to large lateral displacements and is difficult to monitor for small displacements, lacking the ability to perceive potential risks and having significant limitations in use.

[0005] This utility model provides the following technical solution: a warning light with a tension sensor, including an L-shaped fixing plate, two fixing holes are symmetrically opened on the side of the L-shaped fixing plate, and fixing screws are inserted into the fixing holes.

[0012] This solution makes it easier to disassemble the limiting fixing seat and the fixing sleeve.

[0013] Preferred technical solution five: The end of the fixing steel nail is conical.

[0014] This design allows the fixing steel nails to better drive the connecting steel wires into the cap beam.

[0015] Compared with the prior art, this utility model provides a warning light with a tension sensor, which has the following advantages:

[0016] (1) This utility model has a top mounting compartment on an L-shaped fixed plate, in which a PLC integrated machine and a warning light body are installed. A tension sensor body is installed on the L-shaped fixed plate. The tension sensor body is connected to the side of the cap beam on the bridge by a connecting steel wire. The warning light body is located in a position that can be captured by the camera. When the cap beam is displaced, the connecting steel wire will pull the tension sensor body. After the tension sensor body reacts accordingly, it transmits the displacement signal to the PLC integrated machine through a cable. The PLC integrated machine judges the switch of the warning light body, so that the warning light body displays a green light in a safe state and a red light in a dangerous state, so as to be captured by the monitoring camera. This effectively solves the problem of difficult monitoring of blind spots in the monitoring field of view. Attached Figure Description

[0022] Please see Figure 1-4 ,

[0023] Example 1: A warning light with a tension sensor includes an L-shaped fixing plate 1. Two fixing holes 2 are symmetrically opened on the side of the L-shaped fixing plate 1. Fixing screws 3 are inserted into each fixing hole 2. A top mounting compartment 4 is provided at the top of the L-shaped fixing plate 1. A partition 5 is provided in the top mounting compartment 4.

[0024] A PLC all-in-one machine 6 is installed inside the top mounting compartment 4. A warning light body 7 is set on the side of the PLC all-in-one machine 6. Fixing screw grooves 8 are opened around the top of the top of the top mounting compartment 4. A top cover plate 9 is set on the top of the top mounting compartment 4. A mounting opening 10 is opened on the top cover plate 9. Fixing insertion holes 11 are evenly opened around the top cover plate 9. Fixing bolts 12 pass through the fixing insertion holes 11. The bottom end of the fixing bolts 12 is inserted into the fixing screw grooves 8. The top of the warning light body 7 passes through the mounting opening 10.

[0025] The top of the L-shaped fixing plate 1 is fixed with a limiting fixing seat 13. The tensile sensor body 14 is provided inside the limiting fixing seat 13. A fixing sleeve 15 is sleeved on the outside of the tensile sensor body 14. The bottom end of the fixing sleeve 15 is inserted into the limiting fixing seat 13. A connecting steel wire 16 is connected to the tensile sensor body 14. The top end of the connecting steel wire 16 passes through the top end of the fixing sleeve 15. A fixing connecting ring 17 is provided at the end of the connecting steel wire 16. A fixing steel nail 18 is provided on the fixing connecting ring 17.

[0026] Example 2: The difference between this example and Example 1 is that a sealing gasket is provided at the junction of the top cover plate 9 and the top mounting compartment 4.

[0027] This makes the top cover 9 more tightly sealed to the top mounting compartment 4.

[0028] Example 3: The difference between this example and Example 1 is that the inner wall of the limiting fixing seat 13 is provided with an internal thread, the outer side of the bottom end of the fixing sleeve 15 is provided with an external thread, and the limiting fixing seat 13 and the fixing sleeve 15 are connected by threads.

[0029] This makes it easier to disassemble the limiting fixing seat 13 and the fixing sleeve 15.

[0030] Example 4: The difference between this example and Example 1 is that the end of the fixing steel nail 18 is conical.

[0031] This allows the fixing steel nail 18 to better drive the connecting steel wire 16 into the cap beam.

[0032] In this embodiment, traditional warning lights are mostly activated or deactivated by setting a trigger device on one side of the roadbed or bridge to alert people. However, this method is only applicable to large lateral displacements and is difficult to monitor for small displacements. It lacks the ability to perceive potential risks and has significant usage defects.

[0033] In summary, during implementation, the L-shaped fixing plate 1 is first fixed to the bridge pier by fixing screws 3 through the through-hole 2, and the device is located in a position that the monitoring camera can capture. The limiting fixing seat 13 at the top of the L-shaped fixing plate 1 is equipped with a tensile sensor body 14. A connecting steel wire 16 is connected to the tensile sensor body 14. The end of the connecting steel wire 16 is inserted into the side of the cap beam through a fixing steel nail 18 fixed on the fixing connecting ring 17 and kept taut. When the cap beam on the bridge is displaced, the tensile sensor body 14 is pulled by the connecting steel wire 16, and the tensile sensor body 14 can detect the strain of the measured object in real time.

[0034] The strain signal is converted into an analog electrical signal or a digital signal. The signal is transmitted to the analog input module (AI) or digital input module (DI) on the PLC integrated machine 6 through the cable connecting the tensile sensor body 14 and the PLC integrated machine 6. The PLC samples, filters, and performs analog-to-digital conversion on the signal. If it is an analog signal, the PLC on the PLC integrated machine 6 performs internal logic operations, makes judgments, and controls the output. When the threshold is set: a safety threshold such as "maximum allowable strain value" or "load limit" is preset in the PLC program.

[0035] Logical operation: The PLC compares the real-time collected strain data with the threshold:

[0036] If the data exceeds the threshold, an output signal is triggered to the control circuit of the warning light body 7, which can also be linked to other devices such as motor shutdown and valve closure.

[0037] If the data is normal, the main body of the warning light 7 remains off or constantly green.

[0038] After receiving the output signal from the PLC in the PLC all-in-one machine 6, the main body 7 of the warning light will issue an alarm to the operator through changes in light color, such as flashing red, buzzer alarm, or screen prompt. If the integrated display screen is used, the alarm can be recorded by the PLC for traceability.

[0039] This device can accurately monitor minute displacements of the cap beam, allowing users to take timely and effective measures to address potential risks, making the overall monitoring function more comprehensive.
